If you know in advance you are likely to need more than 8MB of stack,
the application can easily do a setrlimit() to increase the limit. At
least under Linux, the default 8MB limit is just a soft limit, not a
hard one, so the application can raise it at will without requiring
any special privileges.

And to get your svn dump to work just the once, you can manually
change the stack limit at the command line without having to modify
the application at all with

        $ ulimit -s unlimited

for bash. Other shells probably have different
incantations for this: for csh it's

        $ limit stacksize unlimited
